JOHANN HEGEDUS, OF NEWV YORK, N. Y.

EXTENSION-TABLE.

- SPECIFICATION forming part of Letters Patent No. 304,929, dated September 9, 1884.

Application filed February 21, 1884. (No model.)

To all whom it may concern.-

Be it known that I, JOHANN Hnenniis, a citizen of Austria-Hungary, residing at New York, in the county and State of New York, have invented new and useful Improvements in Extension-Tables, of whichthe following is a specification.

This invention relates to a table provided with two leaves, either or both of which -can be pushed beneath the table-top or drawn out and secured in a position level with said top.

The peculiar and novel construction of my table is pointed out in the following specification and illustratedin the accompanying drawings, in which Figure 1 represents an inverted plan when the extension leaves are pushed in. Fig. 2 is a vertical section of the same in the plane 00 ac, Fig. 1. Fig. 3 is an inverted plan when the extension-leaves are drawn out. Fig. iis a vertical section of the same in the plane 1 1 Fig. 3.

Eimilar letters indicate corresponding parts.

In the drawings, the letter A designates the frame, which is supportedby the legs B, and which is provided with acentral slat, O, which is secured on the end pieces of the frame and extends beyond the same, and serves to support the tabletop D, said top being firmly secured to this slat by screws a a or by other suitable means. By the slat O the top D is raised above the frame A, so as to leave spaces on each side of the slat for the extensionleaves E E. These leaves are provided at their inner edges with tongues b b, which, when the leaves are pushed in, engage with grooves c c in the opposite edges of the slat O, and when the leaves are drawn out said tongues engage with grooves (l d in the edges of the top D. Each of the leaves E E is supported by two slides, a 0, e 0, respectively, and the slides e e fit into guide-grooves f in the side bar 9 of the frame A, while the slides c c fit into guide-grooves f in the side bar With the side bars, 9 g, and the central slat, O, are combined braces h h, and these braces are so situated that they form additional guides for the slides e e and e 6, respectively, and that the operation of m0ving the leaves E E in or out can be performed with ease, and the danger that the guides may become jammed in their guide-slots is avoided. Each of the guides e e, c e is provided with a shoulder, 2' or i, and if the leaf E is drawn out the shouldersiof the guideseebear against springs j j, while, when the leaf E is drawn out, the shoulders of the guides e e bear against springs j j. These springs are secured to the side bars, 9 g, respectively, and their object is to retain the tongues b b of the leaves E- E in gear with the grooves (Z (Z in the opposite edges of the table-top D, as shown in Fig. 4. hen it is desired to push in one of theleaves, said leaf must be drawn out against the action of the springs j j or j 1 until the tongues b or 1/ clear the groove (2 or d. Then the leaf can be depressed and pushed in beneath the tabletop D. Vhenthe leaves E E are drawn out, they are sustained against a downward pressso that they can be turned into their working position, as shown in Figs. 1 and 2.

1. The combination of the frame A, having the side bar 9, provided with guide-grooves, the taple-top D, having the grooved d, the central slat, O, interposed between the frame and top and having the groove 0 c, the slides e, and the extension-leaf E, having the tongue or tongues b on its inner edge, substantially as described.
